Figure 3:

Operations for creating and moving asters are composed to make different desired patterns and trajectories. a, Sketch for using excitation cylinders to simultaneously pattern asters of different sizes. b, Resultant pattern of asters corresponding to (a). c, Illustration of simultaneous control of two different aster trajectories, as indicated by the dashed arrows. d, Time lapse and the 2D trace of the aster trajectories corresponding to (c). The trajectory trace is color-coded to represent progression in time. e, Dynamically projected spiral to illustrate curvilinear motion. f, time lapse and the 2D trace of the aster trajectory. Time is color coded as in (d).
